Abstract: A reception apparatus includes receiver and processing circuitry. The receiving circuitry is configured to receive a broadcast stream. The processing circuitry is configured to extract a service list table (SLT) from the broadcast stream. The SLT includes service information for each of a plurality of services in the broadcast stream. The processing circuitry is configured to determine whether the broadcast stream includes a digital rights management (DRM) service that is supported by the reception apparatus based on service category information in the service information for the plurality of services in the broadcast stream. The processing circuitry is configured to acquire DRM-related information, which is associated with the reception apparatus and delivered in the DRM service, based on a determination that the broadcast stream includes the DRM service that is supported by the reception apparatus.
